PURPOSE:To simplify input operation and to shorten a score generation processing time by inputting scale information according to how many times a key depressed. CONSTITUTION:This processor is provided with a key input means 100 which generates a signal each time a key is pressed, a counting means 200 which counts how many times the key is generated by the key input means 100, and a signal processing means 300 which generates an information process code signal indicating the pitch of a scale corresponding to the counted frequency of generation. Then, the pitch of the scale is indicated with the frequency of depression of the key. Consequently, indicating operation for the scale is facilitated and the time required for score generation is shortened. |
